9 reasons why we choose Liniar for Windows

In just over two years, Window Supply Company has very quickly become one of the largest fabricators of uPVC windows in Scotland. One of the factors contributing to this is undoubtedly due to the calibre of industry-leading suppliers we choose to partner with. As pioneers of the Liniar windows profile in Scotland, we know that Liniar provides the most technically advanced uPVC window system in the UK.

However, many people, who are unfamiliar with the liniar profile chart and what it offers to clients, tradespeople and suppliers alike may ask themselves, are liniar windows any good? In short, yes!

Here are 9 reasons why we choose Liniar.


Liniar is a leading UK manufacturer of uPVC profiles, and the Liniar windows profile is the first brand new profile of its kind in nearly two decades. Liniar award-winning profiles are designed completely from scratch to incorporate the very latest developments in window engineering technology. Liniar continues to invest in research and new product development to push the boundaries of product innovation meaning we manufacture the very latest in window technology.

Liniar Windows are Environmentally friendly

As a company invested in protecting the environment, we choose Liniar because their uPVC profiles are manufactured using 100% lead-free materials minimising the impact on the environment. Additionally, all elements of a Liniar window are fully and easily recyclable.

Liniar is Designed for installers

As a supplier to trade, it is essential we deliver products that address the challenges of our customers and Liniar’s patented designs were built with the installer in mind. This means that Liniar windows are simple to fit, saving our customers precious time and money on the job. Matching products also include patio, bi-fold, French and residential doors to give installations a seamless finish.

Liniar Windows are Thermally efficient

Thermal efficiency remains the single most popular reason for replacing old windows and the Liniar 70mm window system is the most thermally efficient system on the market. This is achieved by removing unnecessary steel reinforcement and instead developing the latest multi-chambered technology to lock the heat inside. Liniar’s patented double-action bubble gaskets maintain a tight weather seal, and a unique glazing flipper reduces cold transfer.

Liniar is Made in Britain

In April 2018, Oxford Economics published a report called The True Impact of UK Manufacturing. The report contained statistics about how important manufacturing is to the UK economy. The report found that for every £1 million that UK manufacturing contributes to UK GDP, a further £1.5 million is supported across the wider economy. For each job in manufacturing, a further 1.8 are supported in other areas of the economy. Published well in advance of the impact of COVID19, it is now more important than ever to buy British. Liniar profiles are extruded in Derbyshire, UK, which boasts the largest mixing plant in the UK.

Liniar Windows are Strong and secure

The security of a window frame is a high-ranking priority for consumers and Liniar windows are tested to the latest security standards achieving PAS24 and Secured by Design making Liniar windows compliant to Part Q building regulations. Liniar has also invested in a robotic for cyclic testing; ensuing products endure the rigours of daily living.

Colour range

Liniar has one of the largest selections of foil colours in the UK, with 37 stocked foil shades over 5 substrate colours with hundreds of more colour options available on longer lead times.


The future depends on the sustainable work we do today, and Liniar is committed to protecting the planet. In April 2021, the latest audit of the ISO 14001 accreditation showed Liniar was a staggering 53.95% ahead of its Climate Change Agreement for Q1 2021. This puts Liniar ahead of its quarterly target to reduce its carbon footprint, saving 20,410 metric tonnes of Carbon.
